	<htmltext>Maybe I've watched too much science fiction, but building self-replicating robots never seems to turn out quite the way you'd want. A few examples: the NS5 robots from I, Robot, the Decepticons - although those weren't man-made, and the Cylons. Is this something we want to recreate? Because humanity only survived the Cylon invasion thanks to the Galactica, so maybe NASA should think about building a few Battlestars before they go messing around with things they don't fully understand.
